Re: Samsung PLASMA PS50C450B1W: Y-Buffer board Problem!!

I'm technician in electronics. I was working for 4 years in telecomunication electronic repair. Now I am working in industry electronics.
Flatvparts.com say that they test all the boards, but I'm not sure. I'm not sure that the panel plasma its ok. But I will try replace all the boards. The last chance its replace the psu.
The original fail was clicking the start relay. And the normal solution its replace the xboard. But I replace all the boards and I only get the sound. But the picture its dark. I will tell...

Hello, the original fail its dont start and clicking the start coil. Im technician and the normal solution its replace the x-main and the y-sus boards. After do that the sound its ok but no picture. Ahh I replace too the buffer board.
I have a problem with two voltages, Va and Vs. These voltages start ok but go down too fast. If I disconnect these boards these voltages dont go up. I'm dont know what to do. The last chance its to replace the PSU. I purchase all the boards used in flattvparts.com. I'm waiting for the psu. Thanks to somebody who can help me in this fail. I will be grateful....
